fix: every number on a Programs card and hierarchy row describes one population (#699, #643)

[Taleef7]

Closes #643, closes #699.

Two places where a number sat next to another that described a different population, and nothing on screen said so.

#699: Programs has no date range

• The problem. The header's Date range scoped each card's "Open cases (N)" but not the rate or chips beside it. On the Maui sandbox, "Last 7 days" put "Overdue 1,643" next to "Open cases (364)" and left every trend box empty.
• The fix. Rates are measurement-year figures, so Programs and the hierarchy no longer send the range. The header hides the Date range selector on /programs and /programs/*, and keeps it on every other page. A range already in the URL is kept for those pages.
• Also fixed. The card's "Open cases (N)" link dropped the site. With Kihei Clinic selected, CMS125 read "Open cases (340)" but opened Cases for all sites (1,643). The link now carries the site.

#643: the hierarchy shows what its rate is made of

• The problem.
  • The table showed Evaluated · Compliant · Compliance, but the rate divides by the population, which was never shown. Patients reading "Evaluated 6 · Compliant 1" showed 50%, 100%, 25% or 33.3%.
  • Filtered to CMS122, it showed Compliance 53.9% while the CMS122 card read Poor control 46.1%.
• The fix. The columns are now In population · Compliant · Compliance. Each row's rate, numerator and denominator come from displayRate, the function the Programs card uses. Filtered to one lower-is-better measure, the table reads Poorly controlled · Poor control, as its card does. A note under the filters says what the rate divides by.
• Unchanged. The all-measures Compliance values: the denominator is the same one the backend's complianceRateOf divides by.

Frontend only; the API still accepts from/to.

Tests

• layout.date-range.test.tsx: the selector is hidden on the three Programs paths in both the header and the mobile bar, and kept on /worklist, /cases, /runs and /programsx.
• programs/__tests__/page.range.test.tsx: no from/to is sent even when a range is set, and "Open cases" carries the site.
• hierarchy/__tests__/page.numbers.test.tsx:
  • the column set;
  • two patients with equal Evaluated/Compliant counts at 50% and 25%;
  • exclusions and out-of-population rows left out of In population;
  • CMS122 read as Poor control 75%;
  • no range sent.

Each test was mutation-checked: 10 mutations, all caught. The full frontend suite (577 tests), lint and build pass locally.
